installed.

CAUTION!

CLEANOUT OF THE HEAT EXCHANGER, FLUE PIPE, CHIMNEY, AND

DRAFT INDUCER (IF USED), IS ESPECIALLY IMPORTANT AT THE END

OF THE HEATING SEASON TO MINIMIZE CORROSION DURING THE

SUMMER MONTHS, CAUSED BY ACCUMULATED ASH.

CAUTION!

INSPECT FLUE PIPES, FLUE PIPE JOINTS AND FLUE PIPE SEALS

REGULARLY TO ENSURE THAT SMOKE AND FLUE GASES ARE NOT

DRAWN INTO, AND CIRCULATED BY, THE AIR CIRCULATION SYSTEM.

Rules for safe installation and operation

Read these rules and the instructions carefully. Failure to follow them will cause a

hazard that could result in death, serious bodily injury, and/or property damage.

Your Furnace is designed to be installed in a parallel air ﬂ ow arrangement with a gas or oil-

ﬁ red forced air upﬂ ow-type central furnace, or it may be installed as a central furnace.

1. Check your local codes. The installation must comply

with their rulings.

2. Do not install this furnace in a mobile home or trailer.

3. Always connect this furnace to a chimney and vent to

the outside. Never vent to another room or inside a

building.

4. Do not connect this furnace to an aluminum Type B gas

vent. This is not safe and is prohibited by the National

Fire Protection Association Code. This furnace requires

a masonry or Listed Factory Built Chimney for residential

type or Building Heating Appliance Chimney. Use a 6"

diameter chimney or larger, that is high enough to give

a good draft.

5. Be sure that if a masonry chimney is used, it is safely

constructed and in good repair. Have the chimney

inspected by the Fire Department or an inspector.

6. Inspect chimney connector and chimney before and

frequently during the heating season for any deposit

of creosote or soot which must be removed.

7. Provide air for combustion into the room where the fur-

nace is located. If the intake is not in the same room,

air must have free access to the room.

8. CAST IRON PARTS MUST BE "SEASONED" TO AVOID

CRACKING, BUILD ONLY SMALL FIRES ON FIRST

USE.

9. To prevent injury, do not allow anyone to use this fur-

nace who is unfamiliar with the correct operation of the

furnace.

10. For further information on using your furnace safely,

obtain a copy of the National Fire Protection Association

(NFPA) publication "Chimney's, Fireplaces and Solid

Fuel Burning Appliances" NFPA 211. The address of

the NFPA is Batterymarch Park, Quincy, MA 02269.

11. Keep the ashpit section free of excess ashes. Do not

allow ashes to stack higher than the sides of the ash

pan.

12. DISPOSAL OF ASHES- Place ashes in a metal container

with a tight ﬁ tting lid. Keep the closed container on a

noncombustible ﬂ oor or on the ground, well away from

all combustible materials. Keep the ashes in the closed

container until all cinders have thoroughly cooled. The

ashes may be buried in the ground or picked up by a

refuse collector.

13. CAUTION- The special paints used on your furnace

may give off some smoke while they are curing dur-

ing ﬁ rst few ﬁ res., Build small ﬁ res at ﬁ rst. The metal

used in construction of the furnace and duct work has

a light coating of oil. This could give off smoke and/or

odor from registers when furnace is used for the ﬁ rst

time. This should disappear after a short period of time.

Once this burn-off has occurred, it should not reoccur.

14. CARING FOR PAINTED PARTS- This furnace has a

painted outside jacket, which is durable, but it will not

stand rough handling or abuse. When installing your

furnace, use care in handling. Clean with soap and

warm water when furnace in not hot. DO NOT use

any acids or scouring soap, as these wear and dull

the ﬁ nish. DISCOLORATION WILL OCCUR IF THE

FURNACE IS OVERHEATED. FOLLOW OPERATING

INSTRUCTIONS CAREFULLY.

15. Keep the feed and ash doors closed at all times except

while tending the furnace.

CAUTION

DO NOT OPERATE WITH THE FEED AND/OR ASH

DOOR OPEN. THIS FURNACE IS DESIGNED FOR

THERMOSTATIC OPERATION. OPERATION WITH

ANY OF THESE DOORS OPEN WILL OVERHEAT

AND DAMAGE THE FURNACE.

WARNING

NEVER STORE FLAMMABLE LIQUIDS, ESPECIALLY

GASOLINE, IN THE VICINITY OF THE FURNACE.

CAUTION

GASES THAT ARE DRIVEN FROM FRESH COAL

MUST BE BURNED OR THEY WILL ACCUMULATE

AND EXPLODE. NEVER SMOTHER A FIRE WHEN

ADDING FRESH COAL.

CAUTION

NEVER USE GASOLINE, GASOLINE-TYPE LAN-

TERN FUEL, KEROSENE, CHARCOAL LIGHTER

FLUID, OR FLAMMABLE LIQUIDS TO START OR

"FRESHEN UP" A FIRE IN THE FURNACE.

Your HOTBLAST Furnace is designed to be a supplemental

or central heating source for your home. This Solid Fuel

Furnace may be installed in conjunction with a properly oper-

ating central furnace that is listed or certiﬁ ed in accordance

with nationally recognized safety standards and equipped

with the required controls and other safety features and

which has been installed in accordance with appropriate

standards of the National Fire Protection Association with

installation clearances speciﬁ ed in the furnace nameplate

marking. The installation must be accomplished by a qualiﬁ ed

agency (one who is engaged in, and is responsible for, or is

thoroughly familiar with the installation and operation of the

gas, oil, and solid fuel burning heating appliances, who is

experienced in such work, familiar with all the requirements

of the authority having jurisdiction.) The installation shall

be in strict accordance with the manufacturer's installation

instructions furnished with the solid fuel furnace.

The chimney connector of the furnace is to be installed to

provide clearances to combustible material not less than

speciﬁ ed in the individual classiﬁ cations and marked on the

furnace. The chimney connector must be connected to a

chimney suitable for use with residential type or building

heating appliances which burn solid fuel.

The Furnace is designed to operate in either parallel or

series air ﬂ ow arrangement with the central furnace or as

a central furnace.

CENTRAL FURNACE INSTALLATION

As a central furnace, the unit functions independently of any

other system. The blower will come on when the plenum

temperature reaches the setting on the blower control.

PARALLEL INSTALLATION (U.S. ONLY)

The design is such that when the blower comes on, the blower

on the central system also comes on. The blower will only

come on when the temperature in the plenum has reached

the setting on the blower control. This is to insure that there

is sufﬁ cient warm air in the system to make it efﬁ cient for

the unit to operate. When the central system thermostat

calls for heat, the central system will operate by the burner

igniting and the blower coming on. It is possible that both

systems will operate simultaneously. It is recommended

that for the most efﬁ cient use of your HOTBLAST Furnace,

that it be ﬁ red as much as possible in order to reduce the

demand on your existing central heating system. This unit

has an optional forced draft kit that operates from a wall

thermostat. When the temperature falls below the setting

on the wall thermostat, the forced draft will come on (U.S.

Stove Option 11/DIKL)

The warm air supply outlet of the HOTBLAST Furnace

shall not be connected to the cold air return of the central

furnace, because the possibility exists of components of the

central furnace overheating and causing the central furnace

to operate other than is intended.

SERIES INSTALLATION

This type of installation uses only the blowers of the existing

central furnace. The solid fuel fan/limit control must also

control the functions of the existing furnace. All electrical

power must come from a single branch circuit.

LOCATING THE FURNACE

1. The furnace should be located in the same room as the

central system and as close as possible, but not closer

than 9". There should be no wall between the furnace

and the warm air outlet duct that is connected directly

to the warm air outlet plenum of the central furnace.

(See Fig. 4)

2. Place the furnace on a noncombustible ﬂ oor.

3. Check ﬁ gures 3 through 5. Be sure you have the clear-

ances shown below from the furnace and the connector

pipe to combustible surfaces. If you have a solid brick

or stone wall behind your furnace, you can place the

furnace as close as you wish to the wall. If the wall is

only faced with brick or stone, treat it as a combustible

wall.

Chimney Connection

MASONRY CHIMNEY

Before using an existing masonry chimney, clean the chimney

and inspect the ﬂ ue liner to be sure it is safe to use. Make repairs

before attaching the furnace. The connector pipe and ﬁ ttings you

will need to connect directly to a masonry chimney are shown.

The chimney connection should be as short as possible.

If the connector pipe must go through a combustible wall before

entering the masonry chimney, consult a qualiﬁ ed mason or

chimney dealer. The installation must conform to local ﬁ re codes,

and N.F.P.A. 211.

DO NOT CONNECT THIS FURNACE TO A CHIMNEY

FLUE SERVING ANOTHER APPLIANCE.

The chimney used for a furnace must not be used to ventilate the

cellar or basement. If there is a cleanout opening at the base of

the chimney, close it tightly.

LISTED FACTORY BUILT CHIMNEY

Carefully follow chimney manufacturer's instructions. Use only a

Listed Residential Type or Building Heating Appliance Chimney.

If your chimney starts at the ceiling (Fig. 7), you will need enough

6" pipe to reach the ceiling.

The top of the chimney must be at least 3 feet above the roof

and be at least 2 feet higher than any point of the roof within 10

feet (Fig. 7).

IMPORTANCE OF PROPER DRAFT

Draft is the force which moves air from the appliance up through

the chimney. The amount of draft in your chimney depends on the

length of the chimney, local geography, nearby obstructions and

other factors. Too much draft may cause excessive temperatures

in the appliance. Inadequate draft may cause backpufﬁ ng into the

room and ‘plugging’ of the chimney.

“Inadequate draft will cause the appliance to leak smoke into the

room through appliance and chimney connector joints.”

“An uncontrollable burn or excessive temperature indicates ex-

cessive draft.”

Take into account the chimney’s location to insure it is not too

close to neighbors or in a valley which may cause unhealthy or

nuisance conditions.

1. The crimped end of the chimney connector ﬁ ts inside the furnace

ﬂ ue collar. Install additional chimney connectors and elbow

with the CRIMPED END TOWARD THE FURNACE. This will

allow any condensation in the ﬂ ue to run back into the furnace.

Use 6" dia. steel pipe and elbows for connection to chimney.

Never use less than 24 gauge and although blued steel is

satisfactory, high temp painted black is much more desirable.

(See Figure 8)

2. Slope any horizontal pipe upward toward the chimney at least

1/4 inch for each foot of horizontal run.

3. You must have at least 18 inches of clearance between any

horizontal piping and the ceiling.(See Fig. 5)

4. The chimney connector must not extend into the chimney ﬂ ue.

(See Fig. 9)

5. Seal each chimney connector pipe joint with furnace cement.

Also seal the pipe at the chimney.

6. Use 3 sheet metal screws at each chimney pipe joint to make

the piping rigid.

7. The chimney connector may include a section for a barometric

draft regulator between the furnace and the chimney (Fig. 6,

7, & 10). The barometric draft regulator must be installed in

the same room (same pressure zone) as the furnace.

8. Install the barometric draft regulator strictly in accordance

with the instructions that are provided with the barometric draft

regulator.

9. A solid damper must be used in the chimney connecting pipes

between the ﬂ ue collar and the chimney. When used in conjunc-

tion with a barometric draft regulator, the solid damper must be

placed between the barometric and the chimney. (See Fig. 6,

7, & 10)

ADJUSTING THE BAROMETRIC DRAFT

REGULATOR

1. Drill a hole in the chimney connector within 18" of the ﬂ ue collar

below the barometric draft regulator just large enough for the

tube of the manometer.

2. Build a ﬁ re after all chimney connections have been made.

3. Use a manometer to measure the draft in the ﬂ ue.

4. Adjust the Barometric Draft Regulator to obtain a draft of 0.05

- 0.06" W.C. under stable ﬁ re conditions.

CONNECTION OF CHIMNEY CONNECTOR TO A MASONRY CHIMNEY

THROUGH A COMBUSTIBLE WALL

Figure 8 shows how to connect the chimney connector of a heater to a masonry chimney through a combustible wall.

There are ﬁ ve allowable ways that a chimney connector can be connected to a masonry chimney by passing through a combustible

wall. NFPA Standard 211 allows the following wall pass-through systems.

Figure 11

1. Use a minimum 3-1/2" thick brick masonry wall framed into the combustible wall. A ﬁ reclay liner (ASTM C315 or

equivalent) having a 5/8" minimum wall thickness must be used and it must be at least 12" away from any material

that could catch ﬁ re. The inside diameter of the ﬁ reclay liner shall be sized for the proper snug ﬁ t of a 6" diameter

chimney connector pipe. The ﬁ reclay liner shall run from the outer surface of the brick wall to, but not beyond, the

shall be securely fastened to wall surfaces on all sides

and shall be sized to ﬁ t and hold the chimney section.

Fasteners used to secure chimney sections shall not

penetrate chimney ﬂ ue liner. See Part C.

4. Use an 8" inside diameter solid insulated listed factory-

built chimney length which has 1" or more of solid insula-

tion. The minimum length of this chimney section shall be

12" and will serve as a pass-through for the 6" diameter

chimney connector. There must be at least a 12" air

space between the outer wall of the chimney section and

any combustible materials. The chimney section shall

be concentric with and spaced 1" away from the chimney

connector by means of sheet steel support plates on

both ends of the chimney section. The opening in the

combustible wall shall be covered and the chimney sec-

tion supported on both sides with sheet steel supports

which are at least 24 gauge (0.024") in thickness. The

sheet steel supports shall be securely fastened to wall

surfaces on all sides and shall be sized to ﬁ t and hold

the chimney section. Fasteners used to secure chimney

sections shall not penetrate chimney ﬂ ue liner. See Part

5. A listed factory-built wall pass-through system may be

purchased and installed according to the instructions

packaged with it to provide a safe method of passing

the chimney connector through a combustible wall for

connection to a masonry chimney.

Additional requirements pertaining to Figure 8 and

the above wall pass-through systems:

1. Insulation material used as part of wall pass-through

system shall be of noncombustible material and shall

have a thermal conductivity of 1.0 Btu • in./ft.² • °F (4.88

kg • cal/hr • m² • °C) or less.

2. All clearances and thicknesses are minimums: larger

clearances and thickness are acceptable.

3. A chimney thimble, as shown for 3" and 4" above (Parts

C and D) shall be for types "3" and 4" connections to

facilitate removal of the chimney connector for cleaning.

The chimney thimble shall be of ASTM C315 ﬁ reclay with

5/8" minimum wall thickness, or material or equivalent

durability. The inside diameter of the thimble shall be sized

for the proper snug ﬁ t of a 6" diameter chimney connector

pipe. The thimble shall be installed without damage to

the chimney ﬂ ue. The thimble shall extend through the

chimney wall to, but not beyond, the inner surface of the

chimney ﬂ ue and shall be permanently cemented in place

with high temperature cement.

4. A chimney connector to a masonry chimney, except for

2" above (Part B), shall extend through the wall pass-

through system to the inner face of the chimney ﬂ ue, but

not beyond. It does not have to be fastened in place so

long as it cannot accidently be pulled out of the chimney

or shoved into the chimney ﬂ ue. If fasteners are used

to secure the chimney connector to a masonry chimney,

the fasteners shall not penetrate the chimney ﬂ ue liner.

5. Any material used to close up any opening for the con-

nector shall be noncombustible.

PART E - (Figure 12)

In addition to the methods shown by A, B, C, and D of

Figure 12, a listed factory-built wall pass-through sys-

tem may be purchased and installed according to the

instructions packaged with it to provide a safe method

of passing chimney connector through a combustible

wall for a connection to a masonry chimney.

If the chimney connector does not have to pass through a

combustible wall to get to a masonry chimney, simply con-

nect the chimney connector directly to the masonry chim-

ney's chimney thimble as described and shown by parts C

and D of Figure 12. Remember, the chimney connector

should extend into the chimney thimble to the innerface of

the chimney ﬂ ue but not beyond; if the chimney connector

is extended through the chimney thimble into the chimney

ﬂ ue, resistance to the ﬂ ow of smoke and gases up the chim-

ney will occur; that ﬂ ow resistance will have an adverse

affect on the operation and performance of the heater and

venting system.

INSTALLATION

Please see all methods of Installation at the rear of

this booklet.

This is a furnace, not a free standing stove. You must direct

heated air from 8" outlets away from the furnace, or it will

not function properly.

1. This installation must be done by a qualiﬁ ed heating

equipment installer.

2. The installation is to be done in compliance with National

Fire Protection Association installation standards: No.

89M, 90B, 211, 70 (National Electrical Code) and Uniform

Mechanical Code 913, 6-4, in the states where applicable.

(Their code offers connecting smoke pipe connectors

into chimney with other fuel burning appliances.)

3. Rooms large in comparison with size of the appliance:

a) Wood or Coal Burning Furnace needs air for combus-

tion and circulation to house.

b) Provision must be made to make up this air and not

starve gas or oil furnace of combustion air.

c) Have the "Authority Having Jurisdiction" determine

that air is of adequate makeup. (Reference N.F.P.A.

Nos. 30&54, Code for Installation of Gas & Oil Equip-

ment).

4. Have the "Authority Having Jurisdiction" to inspect all

chimneys and installations for adequate venting and for

compliance with standard and local codes and regula-

tions regarding installation of wood burning appliances.

5. Installation for Supplemental Heat Application to Existing

Central System.

a) Place Wood or Coal Burning Furnace so that the

chimney connector will be as short as practical and

avoiding unnecessary sharp turns in the smoke pipe

connector and the installation of devices that would

create excessive resistance to the ﬂ ow of ﬂ ue gases.

b) Locate the Wood or Coal Burning Furnace as close as

practical to the existing central hot air heating system,

maintaining clearances as stated on the label on the

fuel door.

c) Clearance from combustible materials must comply

with those stated on the label on the side of the unit.

Refer to the clearance table in the front of this manual.

The installation must be made only on a noncombustible ﬂ oor.

d) Install the smoke pipe connector to the chimney

with 26-gauge pipe and elbows (to be purchased

separately), maintaining the proper clearances for the

speciﬁ c model. Seal the smoke pipe in the chimney

with furnace cement. (The chimney connector shall

be securely supported, and joints fastened with sheet

metal screws or rivets.)

e) Install 8" diameter heat pipe to plenum of the central

hot air furnace. Use 26-gauge pipe and connectors (to

be purchased separately). If central air conditioning

is installed in the plenum, install heat pipe above the

air conditioning unit. Secure heat pipe connection

with supports and sheet metal screws.

f) Connect electrical supply in the electrical junction

box that is mounted on the back of the Furnace. See

Wiring Diagram (Fig. 16). Remove the cover from

electrical junction box and connect power supply wires

to wires designated, using wire nuts. The power cord

supplied may be used for installation, if permitted by

local codes and regulations. If the power cord sup-

plied cannot be used, the power supply wiring must

be 90 degrees centigrade in a metal cable and should

be completed by a qualiﬁ ed installer complying with

NFPA Standard No. 70 and local codes.

POWER FAILURE

INSTRUCTIONS

Operation after loss of power:

1. Remove ﬁ lter if provided

2. Do not expect to keep home at normal temperatures.

3. Do not load fuel above bottom of feed door.

The top down method of ﬁ re building is recommended for this

appliance. After making sure that the stove air intake controls

are fully open (completely pull-out towards you), Place the

largest pieces of wood on the bottom, laid in parallel and

close together. Smaller pieces are placed in a second layer,

crossways to the ﬁ rst. A third layer of still smaller pieces is

laid crossways to the second, this time with some spaces

between. Then a fourth layer of loose, small kindling and

twisted newspaper sheets tops off the pile.

Higher efﬁ ciencies and lower emissions generally result

when burning air dried seasoned hardwoods, as compared

to softwoods or to green or freshly cut hardwoods.

DO NOT BURN:

1. Garbage;

2. Lawn clippings or yard waste;

3. Materials containing rubber, including tires;

4. Materials containing plastic;

5. Waste petroleum products, paints or paint thinners, or

asphalt products;

6. Materials containing asbestos;

7. Construction or demolition debris;

8. Railroad ties or pressure-treated wood;

9. Manure or animal remains;

10. Salt water driftwood or other previously salt water

saturated materials;

11. Unseasoned wood; or

12. Paper products, cardboard, plywood, or particleboard.

The prohibition against burning these materials does

not prohibit the use of ﬁ re starters made from paper,

cardboard, saw dust, wax and similar substances for

the purpose of starting a ﬁ re in an affected wood heater.

Burning these materials may result in release of toxic fumes

or render the heater ineffective and cause smoke.

Dead wood lying on the forest ﬂ oor should be considered

wet, and requires full seasoning time. Standing dead wood

can usually be considered to be about 2/3 seasoned. Split-

ting and stacking wood before it is stored accelerates drying

time. Storing wood on an elevated surface from the ground

and under a cover or covered area from rain or snow also

accelerates drying time. A good indicator if wood is ready to

burn is to check the piece ends. If there are cracks radiating

in all directions from the center then the wood should be dry

enough to burn. If your wood sizzles in the ﬁ re, even though

the surface is dry, it may not be fully cured, and should be

seasoned longer

TAMPER WARNING

This wood heater has a manufacturer-set minimum low burn

rate that must not be altered. It is against federal regulations

to alter this setting or otherwise operate this wood heater

in a manner inconsistent with operating instructions in this

manual.

VISIBLE SMOKE

The amount of visible smoke being produced can be an ef-

fective method of determining how efﬁ ciently the combustion

process is taking place at the given settings. Visible smoke

consist of unburned fuel and moisture leaving your stove.

Learn to adjust the air settings of your speciﬁ c unit to pro-

duce the smallest amount of visible smoke. Wood that has

not been seasoned properly and has a high wood moisture

content will produce excess visible smoke and burn poorly.

Use the included moisture meter to insure your wood has

a 20% or less moisture content.

EFFICIENCIES

Efﬁ ciencies can be based on either the lower heating value

(LHV) or the higher heating value (HHV) of the fuel. The

lower heating value is when water leaves the combustion

process as a vapor, in the case of woodstoves the moisture

in the wood being burned leaves the stove as a vapor. The

higher heating value is when water leaves the combustion

process completely condensed. In the case of woodstoves

this would assume the exhaust gases are room temperature

when leaving the system, and therefore calculations using

this heating value consider the heat going up the chimney

as lost energy. Therefore, efﬁ ciency calculated using the

lower heating value of wood will be higher than efﬁ ciency

calculated using the higher heating value. In the United

States all woodstove efﬁ ciencies should be calculated using

the higher heating value.

The best way to achieve optimum efﬁ ciencies is to learn the

burn characteristic of you appliance and burn well-seasoned

wood. Higher burn rates are not always the best heating

burn rates; after a good ﬁ re is established a lower burn rate

may be a better option for efﬁ cient heating. A lower burn

rate slows the ﬂ ow of usable heat out of the home through

the chimney, and it also consumes less wood.

OVER FIRING

Attempts to achieve heat output rates that exceed heater

design speciﬁ cations can result in permanent damage to

the heater.

ASH REMOVAL AND DISPOSAL

Whenever ashes get 3 to 4 inches deep in your ﬁ rebox or

ash pan, and when the ﬁ re has burned down and cooled,

remove excess ashes. Leave an ash bed approximately

1 inch deep on the ﬁ rebox bottom to help maintain a hot

charcoal bed.

Ashes should be placed in a metal container with a tight-

ﬁ tting lid. The closed container of ashes should be placed

on a noncombustible ﬂ oor or on the ground, away from all

combustible materials, pending ﬁ nal disposal. The ashes

should be retained in the closed container until all cinders

have thoroughly cooled.

SMOKE AND CO MONITORS

Burning wood naturally produces smoke and carbon

monoxide(CO) emissions. CO is a poisonous gas when

exposed to elevated concentrations for extended periods

of time. While the modern combustion systems in heaters

drastically reduce the amount of CO emitted out the chim-

ney, exposure to the gases in closed or conﬁ ned areas can

be dangerous. Make sure your stove gaskets and chimney

joints are in good working order and sealing properly to en-

sure unintended exposure. It is recommended that you use

both smoke and CO monitors in areas having the potential

to generate CO.

GASKETS

It is recommended that you change the door gasket (which

makes your stove door air tight) once a year, in order to in-

sure good control over the combustion, maximum efﬁ ciency

and security. To change the door gasket, simply remove the

damaged one. Carefully clean the available gasket groove,

apply a high temperature silicone sold for this purpose, and

install the new gasket. You may light up your stove again

approximately 24 hours after having completed this opera-

tion. This unit’s ash door uses a 5/8" diameter rope gasket.

This unit's feed door uses a 1/2" diameter rope gasket.

OPERATIONAL TIPS

Operational Tips for Good, Efﬁ cient, and Clean Com-

bustion

• Get the appliance hot and establish a good coal bed

before adjusting to a low burn rate (this may take 30

minutes or more depending on your wood)

• Use smaller pieces of wood during start-up and a

high burn rate to increase the stove temperature

• Be considerate of the environment and only burn

dry wood

• Burn small, intense ﬁ res instead of large, slow burn-

ing ﬁ res when possible

A draft reading of .05 to .06 w.c. is suggested for proper burning of this unit when using wood or

bituminous coal as fuel. When using anthracite coal, this draft reading is a minimum reading.

CAUTION

A chimney ﬁ re may cause ignition of wall studs or rafters which you thought were a safe distance

from the chimney. If you have a chimney ﬁ re, have your chimney inspected by a qualiﬁ ed person

before using again.

• Learn your appliance's operating characteristics to

obtain optimum performance

• Burning unseasoned wet wood only hurts your stoves

efﬁ ciency and leads to accelerated creosote buildup

in your chimney

SERVICE HINTS

Do not expect a furnace to draw. It is the chimney that

creates the draft. Smoke spillage into the house or

excessive build-up of water or creosote in the chimney

are warnings that the chimney is not functioning prop-

erly. Correct the problem before using furnace. Possible

causes are:

1. The connector pipe may be pushed into the chimney

too far, stopping the draft.

2. Do not connect two furnaces or a stove and furnace

into the same chimney ﬂ ue.

3. The chimney used for a furnace must not be used to

ventilate the cellar or basement. If there is a cleanout

opening at the base of the chimney, it must be closed

tightly.

4. If the chimney is operating too cool, water will condense

in the chimney and run back into the furnace. Creosote

formation will be rapid and may block the chimney.

Operate the furnace at a high enough ﬁ re to keep the

chimney warm, preventing this condensation.

5. If the ﬁ re burns well, but sometimes smokes or burns

slowly, it may be caused by the chimney top being

lower than another part of the house or a nearby tree.

The wind blowing over a house or a tree, falls on top

of the chimney like water over a dam, beating down

the smoke. The top of the chimney should be at least

3 feet above the roof and be at least 2 feet higher than

any point of the roof within 10 feet.

6. See page 18 for list of trouble shooting tips.

CHIMNEY MAINTENANCE

Creosote and Soot - Formation and Need for Removal

When wood is burned slowly, it produces tar and other or-

ganic vapors, which combine with expelled moisture to form

creosote. The creosote vapors condense in the relatively

cool chimney ﬂ ue of a slow-burning ﬁ re. As a result, creo-

sote residue accumulates on the ﬂ ue lining. When ignited,

this creosote makes an extremely hot ﬁ re.

When coal is burned, the products of combustion combine

with moisture to form a soot residue which accumulates on

the ﬂ ue lining. When ignited, this soot makes an extremely

hot ﬁ re.

The chimney should be inspected at least twice monthly

during the heating season to determine if a creosote or soot

build up has occurred.

If creosote or soot has accumulated, it should be removed

to reduce the risk of a chimney ﬁ re.

Chimney ﬁ res burn very hot. If the chimney catches ﬁ re,

immediately call the ﬁ re department, then reduce the ﬁ re

by closing the inlet air control. Pour a large quantity of

coarse salt, baking soda or cool ashes on top of the ﬁ re in

the ﬁ rebox.

ATTENTION:

This wood heater needs periodic inspection and repair for proper operation. It is against federal

regulations to operate this wood heater in a manner inconsistent with operating instructions in this

manual.

TROUBLE SHOOTING TIPS FOR WARM AIR FURNACE

1. Problem:

Smoke puffs from furnace

Solution:

A. Check chimney draft. Check for blocked chimney or

ﬂ ue pipe. Use mirror to check chimney clearance.

B. Check ash pit — if it is too full, empty.

C. Make sure furnace room is not too airtight.

D. Make sure all of chimney mortar connections are

airtight.

E. Check ash drawer. Make sure it’s airtight.

F. Check chimney for possible down-draft caused by

taller surrounding trees or objects. Correct with proper

chimney vent cap.

G. Check the possibility of a cold chimney forcing cool

gases backward. Remedied by properly insulating

chimney with non-combustible liner — non-combus-

tible insulation.

H. Fuel may be too green.

I. Make sure no other fuel burning devices are con-

nected to the chimney impairing the draft.

J. Check chimney draft, it should be .06 inches of wa-

ter column. This service is provided by a certiﬁ ed

chimney sweep.

2. Problem:

Inadequate heat being delivered to your home

Solution:

A. Check home insulation — is it adequate?

B. Check hook-up to furnace — is it installed correctly?

C. Cool air inlet may be inadequate or furnace room

too airtight.

D. Your wood fuel may be too low grade. Hardwoods

are recommended.

E. Make sure your hot air duct (and other duct work) is

airtight.

F. If furnace room is warm but your home isn’t, check

back draft dampers.

G. Is air to the blower available?

3. Problem:

Excess smoke or ﬂ ames coming out door when refueling

Solution:

A. Wait 15 seconds and open door SLOWLY — then

refuel.

B. Check length of ﬂ ue pipe to chimney. Your unit should

be within six (6) feet of your chimney.

C. Make sure chimney cap is not too close to the top

of the chimney.

D. Check chimney draft — make sure chimney ﬂ ue pipe

is clean and chimney is of adequate height.

E. Make sure you’re not suffocating the ﬁ re with exces-

sive amounts of unburned wood.

F. Slide bafﬂ e should be pulled out prior to load door

opening.

4. Problem:

Distribution blower vibrating

Solution:

A. Tighten blower wheel to motor shaft.

B. Check for bad fan bearings.

5. Problem:

Distribution blower continues to run or will not run

Solution:

A. Check fan limit or heat sensor and cable.

B. Check to see that blower is properly wired.

(See Wiring and Assembly Instructions).

C. Check fuse box or power source.

D. Check power supply.

6. Problem:

Odor from ﬁ rst ﬁ re

Solution:

A. The odor from new steel should disappear in a few

hours.

B. If the odor remains, call you dealer immediately. A

bad weld can cause a fume leak.

7. Problem:

Excessive Creosote

Solution:

A. Check the grade of wood you are burning.

B. Make sure your unit is serviced by its own proper

chimney.

C. Check length of ﬂ ue pipe and its connections.

D. Make sure you are burning the smallest, hottest ﬁ re

to adequately heat your home.

E. Also see Solutions to Problem one.

8. Problem:

If the ﬁ re goes out or does not hold over night

Solution:

A. Poor Draft.

B. Incorrect damper settings.

C. Improper ﬁ ring methods if burning coal.

D. More combustion air needed.

E. Coal not sized to the furnace. We recommend 1” to

3” diameter pieces of coal.

F. Ashes, if allowed to accumulate in the ash pit, will

not allow passage of the required air for combustion.

Keep ash pit clean.

G. This furnace is not to be used with an automatic

stoker unless so certiﬁ ed.
